After first year of my life in the United States I made a trip to my native country , when I came back and board the immigration service with an apset face and with no knowlage of english they stoped me and wanted to deport me even though I have a green card. The lesson, never ever come to the officers with such emotions. I am flying twice a year and always put mask on my face in front of officers. Hope it will help.
